Some sensors can have more than one pad (case of S5C73M3). In such cases FIMC assumes the last pad of the sensor is the source pad. Signed-off-by:

Add second source media pad for the FIFO data output to FIMC-IS and implement subdev s_stream op for configurations where FIMC-LITE is used as a glue logic between FIMC-IS and MIPI-CSIS or an image sensor. The second source media pad will be linked to the FIMC-LITE video node. For proper configuration the attached image sensor/video encoder properties are needed, like video bus type, signal polarities, etc. For this purpose there is a small routine added that walks the pipeline and returns the sensor subdev.

Add variant data structures for Exynos4212 and Exynos4412 SoC. Add 'const' qualifier for the variant description structures. Also remove has_cam_if flags from FIMC3 on Exynos4210 SoC is it has no interconnections the camera ports. Signed-off-by:

The FIMC FIFO output is not supported in the driver due to some hardware issues thus we can remove some code as out_path is always FIMC_IO_DMA. Signed-off-by:

The counter field is unsigned so >= 0 condition always evaluates to true. Fix this to log events for which counter is > 0 or for all when in debug mode. Signed-off-by:

Setting FIMC_REG_CITRGFMT_FLIP_X_MIRROR bit causes X-axis image flip (vertical flip) and thus it corresponds to V4L2_CID_VFLIP. Likewise, setting FIMC_REG_CITRGFMT_FLIP_Y_MIRROR bit causes Y-axis image flip (horizontal flip) and thus it corresponds to V4L2_CID_HFLIP. Currently the driver does X-axis flip when V4L2_CID_HFLIP is set and Y-axis flip for V4L2_CID_VFLIP. Fix this incorrect assignment by setting proper FIMC_REG_CITRGFMT register bits for ctx->hflip and ctx->vflip. Reported-by:

v4l2_get_timestamp() produces a monotonic timestamp but unlike ktime_get_ts(), it uses struct timeval instead of struct timespec, saving the drivers the conversion job when getting timestamps for v4l2_buffer's timestamp field. Signed-off-by:

Sakari Ailus authored
Define video buffer flags for different timestamp types. Everything up to now have used either realtime clock or monotonic clock, without a way to tell which clock the timestamp was taken from. Also document that the clock source of the timestamp in the timestamp field depends on buffer flags.

G-Scaler src buffer count as well as destination buffer count is increased to 32. This is required for G-Scaler to interface with MFC, as MFC demands 32 capture buffers for some H264 streams. Signed-off-by:

In case of clk_prepare failure, the function gsc_clk_get also prints "failed to get clock" which is not correct. Hence move the error messages to their respective blocks. While at it, also renamed the labels meaningfully. Signed-off-by:

Explicit checks for the JPEG pixel format in soc_mbus_bytes_per_line() and soc_mbus_image_size() are superfluous, because also without them these functions will perform correctly. The former will return 0 based on packing == SOC_MBUS_PACKING_VARIABLE and the latter will simply multiply the user-provided line length by the image height to obtain a frame buffer size estimate. The original version of the "media: soc_camera: don't clear pix->sizeimage in JPEG mode" patch was correct and my amendment, adding these two checks was superfluous. Signed-off-by:

Video Engine Unit (VEU) is an IP block, found in multiple SuperH and ARM- based sh-mobile and r-mobile SoCs, capable of processing video data. It can perform colour-space conversion, scaling and several filtering transformations. This patch adds an initial implementation of a mem2mem V4L2 driver for VEU. So far only conversion from NV12 to RGB565 is supported. Further functionality shall be added in the future. This driver is based on a VEU vidix driver by Magnus Damm. Signed-off-by:
